## Abstract

Compositions comprising starch-acrylic polymers combined with elemental iodine are disclosed. The SAP-I compositions release non-toxic amounts of iodophor iodine in a sustained, controlled manner. Methods of formation and use of the compositions along with methods of creation and use of devices incorporating the compositions in a variety of healthcare and non-healthcare settings are set forth in detail herein.

## Claims

### Claim 1

An antimicrobial composition comprising elemental iodine combined with a starch-polyacrylic graft copolymer to form a dry composition having a starch acrylic polymer-iodine complex, wherein the dry composition comprises elemental iodine at a concentration between twenty percent (20%) and twenty-five percent (25%) by weight, and wherein the dry composition is able to absorb at least eighty (80) times its weight in water.

### Claim 2 (depends on 1)

The antimicrobial composition of claim 1, wherein the antimicrobial composition is formed as a powder.

### Claim 3 (depends on 1)

The antimicrobial composition of claim 1, wherein the antimicrobial composition is formed as a flake.

### Claim 4 (depends on 1)

The antimicrobial composition of claim 1, wherein the antimicrobial composition is formed as a gel.

### Claim 5 (depends on 1)

The antimicrobial composition of claim 1, wherein the antimicrobial composition is formed as a sheet.

### Claim 6 (depends on 1)

The antimicrobial composition of claim 1, further comprising a hemostatic agent.

### Claim 7 (depends on 1)

The antimicrobial composition of claim 1, further comprising a bulking agent.

### Claim 8

A wound dressing comprising: an iodophor formed from elemental iodine adducted to a starch-polyacrylic graft copolymer to form a dry composition having a starch acrylic polymer-iodine complex; and a bandage, wherein the starch acrylic polymer-iodine complex comprises elemental iodine at a concentration between twenty percent (20%) and twenty-five percent (25%) by weight, and wherein the dry composition is able to absorb at least eighty (80) times its weight in water.

### Claim 9 (depends on 8)

The wound dressing of claim 8, wherein the iodophor is formed as a powder or a flake.

### Claim 10 (depends on 9)

The wound dressing of claim 9, wherein the iodophor is incorporated into a poultice.

### Claim 11 (depends on 8)

The wound dressing of claim 8, wherein the iodophor is incorporated into a coated foam.

### Claim 12 (depends on 8)

The wound dressing claim 8, wherein the iodophor is incorporated into a gel.

### Claim 13 (depends on 8)

The wound dressing of claim 8, wherein the iodophor is formed as a sheet.

### Claim 14 (depends on 8)

The wound dressing of claim 8, further comprising a hemostatic agent.

### Claim 15 (depends on 8)

The wound dressing of claim 8, wherein the bandage is an adhesive bandage.

### Claim 16 (depends on 8)

The wound dressing of claim 8, wherein the bandage is a bandage roll.
